Abstract In the paper,we introduced an electric vehicle with Brushless DC motor double closed loop speed control simulation, using PWM modulation method of the system without each circuit of the Brushless DC motor stator phase control, from the transfer from the point of view, on the current detection feedback link in the different times by the current moment value by means of phase shifting method; modules together to form a system simulation; using oscilloscope are suitable for electric vehicle use performance better motor speed curve. Brushless DC motor is an acronym for BLDCM (Brushless DC motor), because of its simple structure, reliable operation, low cost, easy to maintain, the brush motor effectively avoid the mechanical commutation spark, noise, radio interference and short service life of the shortcomings of. While preserving its efficiency, less waste, easy speed advantages. And firstly, we, in this paper the speed single loop PI speed control system is used to speed anti-interference ability was significantly improved, from the non static difference we can run brushless motor. Process from the brush motor development, development of the situation in the development plan in the future is the brushless motor. Structure of the motor is our clear and concise exposition about the working principle for the motor is we discuss about. Finally, the Brushless DC motor in industrial production in all aspects of the situation is we to learn about and understand a little more of several motor models We cite examples, and then the mathematical model is constructed, and then modeled each module using matlab/simulink software, and then use these modules to simulate the system.
